FILLING-REPLENISHING LOOM.

SPEGIETGATION forming part of Letters Patent N o. 691,481, dated January 21, 1902.

Application filed July 8, 1901. Serial No. 67,436. (No model.)

ZIO all zult/011i, if may con/cern,.- Be it known that I, JONAS NoRTHRoP, a subject of the King of Great Britain, residing at Hopedale, county of Worcester, State of Mas-` sachusetts, have invented an Improvement in Automatic Filling-Replenishing Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

In looms furnished with mechanism for effecting a change of filling upon breakage or running out of the same, as distinguished from looms wherein the filling is changed or replenished prior to complete exhaustion of the filling in the shuttle in play, the construction is such that if the filling fails either by breakage or exhaustion while it is being laid in one direction-viz., toward the replenishing mechanism-two additional blank or empty picks will be made before the fresh filling is provided. Supposing that this occurs on half the number of filling failures, a fault is made in the cloth each time, and if the failure occurs when the filling is laid in the other direction ordinarily but one pick will be bare of filling before the fresh supply can be provided.

My present invention has for its object the production of a loom wherein the formation of faults in the cloth, as above mentioned, will be obviated and the number of blank picks reduced to a minimum, thereby improving the quality of the cloth accordingly.

My invention may be used in connection with mechanism to automatically provide the shuttle with a fresh supply of filling in place of the spent supply or with mechanism wherein a fresh or full shuttle is provided when necessary to take the place of the spent or empty one, as Will be manifest hereinafter; but herein I have shown and described one practical embodiment of my invention in connection with replenishing mechanism of the former type. y

Figure l represents a transverse section of a sufficient portion of a loom to be understood, taken at right angles to the axis of the filling-feeder between the end plates or heads thereof. Fig. 2 is a top or plan view of the lay and shuttle-box at the replenishing side of the loom, with the shuttle in the box, and also illustrating the detector for indicating non-continuity of the filling when laid, the replenishing mechanism above the line 0c, Fig. l, being omitted; and Fig. 3 is a side elevation of the detector in normal position, the lay and shuttle-box being shown in section.

The lay A3, slotted at 10, below the shuttlebox BX, to permit the ejection of the spent filling-carrier from the self-threading shuttle S by the entrance thereto o f a fresh fillingcarrier, the filling-feeder F, rotatable on a fixed horizontal axis ct and adapted to carry a plurality of filling-carriers b, to be transferred one by one to the shuttle by the transferrer f', fulcrumedat f on the stand A7, which supports the feeder F, the fixed stop h for the leading filling-carrier of the series, the ratchet as, and a dog,r flo, pivoted on the transferrer at f12 and provided With a tooth jl to operate with the ratchet and intermittingly rotate the feeder in the direction of arrow 36, Fig. l, when the transferrer is returned to the position shown by the action of a strong spring S after transfer of a filling-carrier to the shuttle, may be and are all substantially as in United States Patent No. 664,790, dated December 25, 1900, like partsbeing correspondingly lettered herein. The transferrer is herein shown as having rigidly connected with it an arm f3, depending below the fulcrum f and provided at its lower end With an inturned notched dog f30, Which when engaged by an actuating-bunter, to be described, swings the arm f3 in direction of arrow 30 to depress the transferrer and eect a change of filling, substantially as in the patent referred to. Herein the filling-replenishing mechanism is shown as located at the right-hand side of the loom to provide the instrumentality for laying the filling with a fresh supply of filling when the latter fails, the shuttle being in the shuttlebox BX at the adjacent end of the lay. Referring to Figs. l and 2, brackets h2 on the lay near said shuttle-box form bearing for a rock-shaft b3, having fast upon it a bunter b4, movable in a vertical plane passing through the dog fso, said shaft having secured to it near its inner end a collar b5, provided With a finger h6, the collar and the hub of the IOO bunter preventing longitudinal movement of the rockshaft. A second collar t7, fast on the latter, is provided with a projection or stop bs, and one end of a spring SX, coiled about the shaft, Fig. 2, is secured to the collar, the other end being suitably fixed, as by the bearing h2, the winding of the spring being such that the stop is normally held against the bottom plate U of the shuttle-box with the bunter out of the path of the dog f3() and the finger h6 upturned. It will be manifest that whenever the forward end of the bunter is raised high enough the replenishing mechanism will be actuated on the forward beat of the lay to complete a change of filling when the lay is fully forward. Manifestly with the construction herein illustrated such change must be effected only when the shuttle is in the adjacent shuttle-box BX, as it will be on the pick which thus boxes the shuttle, and if a failure of filling is detected on that same pick and the bunter be through such detection moved into operative position then the change of filling will be effected on the same pick without any lost pick. One means for effecting such result will now be described as a practical embodiment of this part of my invention. f v

A stand mX, having a longitudinal guideway therein, is secured to the breast-beam A40 transversely thereto nearly opposite the inner end of the shuttle-box BX, as shown in Fig. 2, to support a slide-bar M, having at its inner end `a lling detector or fork MX, fulcrumed at m and adapted to at times engage and be tilted by the laid filling when the lay beats up.

Referring to Fig. l, a bell-crank N N' is fnlcrumed at NX on the lower part of the looln-y frame, the arm N having a follower Nwhich travels on a cam CX, fast on the cam-shaft C and so shaped as to effect inward movement ot' the upper end of the upturned arm N at every other pick. The upper end of said arm N is extended through a longitudinal opening 'm' in the stand, Fig. 2, between two cross bars or lugs 5 5 on the slide M, so that Whenever the arm N is rocked to the rear the slide will be moved to bring the detector MX into position to detect continuous or non-continuous filling on theforward beat of the lay. On the side of the slide I have shown a positioning device for the bunter, consisting of a le ver p, fulcrumed at 19X and having at its outer end a lateral lug p to at times engage the finger h6 and rock the buntershaft on the forward beat of the lay. The inner end of the lever p extends beneath a bent leg fm2, secured to or forming a part of the fulcrum 'm of the detector MX, and the normal relative position of the parts is shown in Fig. 3. If now the detector being moved into detecting position, the lay beats up, the tilling, if properly laid, will tilt the detector, depressing the leg m2 and the adjacent end of lever p, elevatingits outer end, so that the lug p will be above the path of the finger Il,

and no change in the normal inoperative position of the bunter hAL will be eected. Should the filling fail, however, its non-continuity will result in leaving the detector MX in the position shown, so that the lug 1J will meet and turn back the finger b and the bunter will coperate with the dog fgo, and a change of filling will be effected. It will be manifest, therefore, that the lling-replenishingis controlled and its actuation effected, broadly speaking, by or through indicating action of the detector that the filling is non-continuous. Remembering that in the construction herein illustrated the filling can be changed only on boxing of the shuttle at one end of the lay, it will be obvious that the detector should cooperate with the filling on alternate picks, and for this reason the detector is with'- drawn into inoperative position on the other picks by or through the cam CX and the intervening devices.

From the foregoing it will be manifest that the change of lling is effected on the pick on which indicating action of the detector occurs, so that no loss of picks will result, and such indicated pick, it will be noted, is in the present instance that one on which the shuttle travels toward and into the shuttle-box nearest the replenishing mechanism. If the filling fails on the opposite pick, no operation of the detector is effected, nor is it necessary; but on the succeeding pick the indicating action of the detector causes filling-replenishment on such pick and only the one pick will be bare of filling. This may, if necessary or desirable, be provided for by any suitable let-back action of the take-up mechanism, which is so well known as to need no explanation to those skilled in the art, nor does it form any part of my invention.

The fulcrum 19X is laterally extended, Fig. 2, and downturned at its outer end to form a shuttle-feeler p5, so located as to sweep over the lay when the latter and the slide M move toward each other, provided the shuttle is properly boxed. If it projects beyond the inner end of the shuttle-box, the feeler p5 strikes it and is swung toward the front of the loom, elevating the lug p to prevent operative positioning of the bunter, so that change of filling will be prevented if the shuttle is improperly boxed. A light spring sw may be mounted on the slide to normally hold the lever p and the detector in the position shown to practically counterbalance the tilting action of the shnttle-feeler. Aspring S10 (see dotted lines, Fig. l) may, if desired or found necessary, be employed to retain the follower N2 on the cam CX, the inward movement of the detector-slide being effected by the combined action of the spring and the weight of the bell-crank N N My invention is `not restricted to the construction shown and described, for various' modifications or changes may be made by those skilled in the art without departing from the spirit and scope thereof.
